Packers.com presents 'Prospect Primer,' a video look at an assortment of draft-eligible players who attended the scouting combine in Indianapolis. Clowney's sacks fell from 13 in 2012 to just three in 2013, while tackles for loss dropped from 23 1/2 to 11 1/2. Also forced just one fumble after forcing eight in his first two seasons combined. Clowney would have been the No. 1 overall pick in the 2013 NFL Draft had he been eligible to enter, but had to stay at South Carolina one more year, and after a subpar season statistically, may or may not be taken No. 1 overall.
